About
Turso is edge-native SQLite (libSQL) with native vector search built in: familiar SQL for your agent's state plus embeddings for RAG memory, all in one database. The free tier needs no credit card and covers about 500 databases, 9 GB of storage, and a billion monthly row reads (per reviews; exact numbers vary). Embedded replicas keep data close to your users.
Details
Free to start. You may need a free key, but no credit card.
